Abstract : Radiocarbon dating of charcoal on podzols along a transect reaching 280 kilometers north of the present tree line from Ennadai Lake indicates that former forests were burnt about 3500 years ago and again from 900 years ago. These forests probably were associated with periods of relatively mild climate. (Author)
